A bit ago I wrote a blog post[1] about building shaded jars to run Fluo applications with Spark. In this post I advocated for building the shaded jars with the versions of Fluo, Accumuo and ZooKeeper on the system. For obtaining the ZooKeeper version, I suggested the following bash command in the post.
ZOOKEEPER_SERVER=localhost ZOOKEEPER_VERSION=`echo status | nc $ZOOKEEPER_SERVER 2181 | grep version: | sed 's/.*version: \([0-9.]*\).*/\1/'` I was looking at this post recently and wondering if there is a better way to get this info for ZooKeeper. Does anyone know a better/different way to accomplish this? Thanks Keith [1]: http://fluo.apache.org/blog/2016/12/22/spark-load/
